Continua'tie'n of application Serial No. 122,381, filed September 6, 190.2, and continuation inpart of application Serial No. 526,856, tiled October 24, 1894. This application filed May 18, 1936, Serial No,

To all w11 om it muy conce'm:

Be it known that I, HowAnnD. Comun', a citlzenofl the United States, residing at Rockford in the comit of WVinneba o and 1,0 machines for preparing warps for weaving .as, for example, a machine for drawing the ends of warp threads through the heddle eyes of loom harness and through the spaces of a loom reed. In such machines the threads-are selected singly and successively from one edge ofa warp and presented to an operating mechanism, movement between the warp and the. selecting mechanism being produced so as to cause one to travel with relation to the other.

@ne of the objects of this invention to provide means for so controlling ,the movement-,producing means that operative relationship shall beestablished between each successive thread of the warp and the thread selecting inechanism., notwithstanding vari-. ations in the widths of warps, I irregular spacingiof the threads of a given warp, and differences in the spacing of the threadsrof different worps.

Another of the objects of this invention is thc. production oi :in impiioved mechanism for placing they ends cfwarp threads, wound upon a, loom beam. throngli the. heddle eyes of Loom harness and through the spaces ofy a loom reed. y

Another object of thc invieniion is to provide improved means for establishing operative relationship between the successive heddle eyes and reed spaces, on the one hund, and the operating mechanism on the other hand. Y

A further object is to provide means for compensating for diierences between thev widths of the harnesses and the reed and the width `of the warp.

A. urthenobfectof the ifivention is theV production of an improved harness and reed carriage.-

The invention further relates to an eyespacing mechanism for 'selecting and releasing .the heddle eyes one-at a, time, lip-st from one harness and then from the r her, alsoto an eye-facing mechanisnifor placing the harness eyes so selected, in p sition to receive the needle carrying a iva p thread.

The invention also relates o the further improve-ments hereinafter set fort-h.

his application is a c ontiination of application Serial No. 122,381 filed by Lne on September G, 1902, which latter application is a continuation of an application tiled by me on October 2i, 189i, Serial No. 526,856.

In the accompanying drawings, Figure l is u side elevation of a Warjv-drawing machine embodying the 'features of my inven` tion, a portion of the Warp carriage and of the frame of' the machine being broken a-Wey and theV harness and reed being omitted. l? ig. 2 is a similar view, but upon a somewhat larger scale, of the principal parts 'of the mechanism. Fig. S is a rear side elevation of the parts shown` in Fig. Fig. 4 is a vertical section through the machine, takenon dotted line 4 4 of Fig. l. Fig. 5 is 'a vertical section onvdotted line 5 of Fig. l, omitting, however, some of the mechA- anism in` the lower part of said figure, in order to Ashow the remainder upon avlarger scale. Fig. 6 is a horiZonta-l section `on dotted line G of Fig. Fig. 6 is a. detail view, showing the end ol the thread-hook. Fig.

Fig. T is a ragmentai perspectivcvi'ew showing the 'position of the .reed and harnesses in the machine, also showing the direction of the Warp threads in passing through thc eyes ofthe harness and the spaces of the reed.'I Fig. 7 is c. sectional 'View through one of the adjustabie hooks for supporting the upper harness bars.

Fig. 11 is a vertical'section on dotted linell 1l of Fig. 10, showing the thread-guide and the thread-holder. Fig. 12 is a fragmental section on dotted .line l2 of Fig. 11. Fig. 13

is a horizontal section on the plane of dotted Fig. 14 is a side elevation of the selector. Fig. 15 is a horivzontal sectional view on dotted line 15-15 of Fig. 14. Fig. 16 is a fragmental view in side elevation, showing the eccentric for ad- 15 justing the vertical angle of the' selector. 'lhis view is taken from the opposite Side of the arm from that shown in Fig. 14. Fig.

17 is a vertical section -on dotted line 17g-17 ot Fig. 6, showing the thread-hook in its 2e lowest position, and the needle in its most U forward position, showing also one of the cye-facers. Fig. 18 is a fragmental view showing in side elqation the .mechanism for feeding the reed through the machine. In 2&5@ this figure, the feeding plunger is shown in its lowest posi-tion, to wit, with its point pressed downward into uf space of the reed. 'fp-Fig. 1S is an enlarged detail View showing 5 itlie lower end of the reed., feed-ing plunger and dent opener. Fig 15:5"` is a transverse ,"section through the A.thread-hook, showing .the groove therein and the forward end of the needle lying in said a view-similar to that o Fig. L18, s owing theyfeeding plunger lifted. Fig.` 19 is a i "transverse section lthrough the feeding plunger on dotted line a-o of Fig. 19, showing the screw for adjusting the side movement ofthe feeding finger. Fig. 20 is a view illustrating the cam and a portion of the connections for vertically moving the reedeeding finger. Fig. 21 is ay View of the cam tha-tactuates the needle'a'rm and the thread-V l hcmk. f Fig. 22 represents in side elevation .a `disconnecting mechanism for e the eyeja'eers', by means of which said eye-facers y may be operated byhand tir-turn theml back and grasp an eye which they have missed, their failure to grasp the harness eye vhaving actuated the stop mechanism by means of one of the automatic stop devices.

Figp isan inner face view of the relatively-movable eye-facer jaw. Fig. 36 illustrates iuv front. elevation an automatic stop mechanism for the eye-facers andthe threadselector. This, mechanism is intended to operate when the facer-jaws fail to grasp an eye or the thread selector fails to catch a thread. vThe figure shows parts broken away to illustrate the trigger-lever acted upon by the thread-selector, also to show the detent device for the belt shifter.

Fig. 37 is an enlarged detail, looking in the direction of thearrows 37 in Fig. 36, showing inside elevation the automatic stop mechanism that operates when the selector fails to catch a thread. Fig. 37 is a perspective view of the trigger lever shown in side elevation in the las rcceding figure. Fig. 38 is a vertical section through the dash-pot for yieldingly arresting the movement of the mechanism when the drive belt is automatically shifted.
